Comment 56 for bug 1057186

Perfect! ttyUSB2 as primary, ttyUSB0 as data:

 (/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2) tty/ttyUSB2 primary
 (/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2) tty/ttyUSB0 data

Will ask Dan to merge this and will forward-port the patch to git master in the following days.
